Practical guidelines and the EMLN R package for handling ecological multilayer networks

Noa Frydman, Shirly Freilikhman, Itamar Talpaz, et al.

Published: 2023-07-25
Subjects: Ecology and Evolutionary Biology, Life Sciences

Network analysis provides a powerful framework to study the complexity underlying the structure, dynamics, stability, and function of ecological systems. By now, analysing single-layered networks is a common practice with clear guidelines and well-established computational tools. Nevertheless, ecological communities are multilayered because they vary over space and time and contain multiple types [...]

Multimodel approaches are not the best way to understand multifactorial systems

Benjamin Bolker

Published: 2023-07-23
Subjects: Applied Statistics, Ecology and Evolutionary Biology

Information-theoretic (IT) and multi-model averaging (MMA) statistical approaches are widely used but suboptimal tools for pursuing a multifactorial approach (also known as the method of multiple working hypotheses) in ecology. (1) Conceptually, IT encourages ecologists to perform tests on sets of artificial models. (2) MMA improves on IT model selection by implementing a simple form of [...]

Collating existing evidence on cumulative impacts of invasive plant species in riparian ecosystems of British Columbia, Canada: a systematic map protocol

Fabio Mologni, Chandra E. Moffat, Jason Pither

Published: 2023-07-22
Subjects: Ecology and Evolutionary Biology, Life Sciences, Plant Sciences

Background Globally, the structure and functioning of foreshore and riparian ecosystems are being dramatically impacted by non-native invasive plant species. Invasive species can outcompete and replace native species, modify geochemical and hydraulic cycles, alter trophic processes, and change the composition and structure of communities above and below ground. However, these impacts are often [...]

The evolutionary dynamics of plastic foraging and its ecological consequences: a resource-consumer model

Léo Ledru, Jimmy Garnier, Océane Guillot, et al.

Published: 2023-07-17
Subjects: Ecology and Evolutionary Biology, Life Sciences

Phenotypic plasticity has important ecological and evolutionary consequences. In particular, behavioural phenotypic plasticity such as plastic foraging (PF) by consumers, may enhance community stability. Yet little is known about the ecological conditions that favor the evolution of PF, and how the evolutionary dynamics of PF may modulate its effects on community stability. In order to address [...]

Application of crime theory in urban ecology, evolution and planning: factors influencing the disappearance of field equipment

Ignacy Stadnicki, Marta Szulkin, Michela Corsini

Subjects: Ecology and Evolutionary Biology, Other Social and Behavioral Sciences, Research Methods in Life Sciences, Urban Studies and Planning

1. Research in urban ecology and evolution relies on the use of deployable scientific equipment. If left unattended in the field, it may be prone to vandalism and theft, especially in the urban space. We empirically applied crime theory, specifically the Routine Activity Theory (RAT), to predict disappearance rates of scientific equipment in an on-going urban ecology research project. 2. [...]

Shifts in internal stem damage along a tropical precipitation gradient and implications for forest biomass estimation

Habacuc Flores-Moreno, Abbey R Yatsko, Alexander W Cheeseman, et al.

Subjects: Ecology and Evolutionary Biology, Life Sciences

Woody biomass is a large carbon store in terrestrial ecosystems. In calculating biomass, tree stems are assumed to be solid structures. However, decomposer agents such as microbes and insects target stem heartwood, causing internal wood decay which is poorly quantified. We investigated internal stem damage across five sites in tropical Australia along a precipitation gradient. We estimated the [...]

Habitat suitability maps for Australian flora and fauna under CMIP6 climate scenarios

Carla Leigh Archibald, David M Summers, Erin M Graham, et al.

Published: 2023-07-05
Subjects: Ecology and Evolutionary Biology

Background: Spatial information about the location and suitability of areas for native plant and animal species under different climate futures is an important input to land use and conservation planning and management. Australia, renowned for its abundant species diversity and endemism, often relies on modelled data to assess species distributions due to the country's vast size and the [...]

Computationally reproducing results from meta-analyses in Ecology and Evolutionary Biology using shared code and data

Steven Kambouris, David Peter Wilkinson, Eden T. Smith, et al.

Published: 2023-07-04
Subjects: Ecology and Evolutionary Biology

Many journals in ecology and evolutionary biology encourage or require authors to make their data and code available alongside articles. In this study we investigated how often this data and code could be used together, when both were available, to computationally reproduce results published in articles. We surveyed the data and code sharing practices of 177 meta-analyses published in ecology and [...]

Biogeographical distributions of trickster animals

Shota Shibasaki, Ryosuke Nakadai, Yo Nakawake

Published: 2023-07-03
Subjects: Arts and Humanities, Ecology and Evolutionary Biology

Human language encompasses almost endless potential for meaning and folklore can theoretically incorporate themes beyond time and space. However, actual distributions of the themes are not always universal and their constraints remain unclear. Here, we specifically focused on zoological folklore and aimed to reveal what restricts the distribution of trickster animals in folklore. We applied the [...]

Lipid Metabolism in Parasitoids and Parasitized Hosts

Mathilde Scheifler, Léonore Wilhelm, Bertanne Visser

Published: 2023-06-30
Subjects: Biology, Ecology and Evolutionary Biology, Entomology, Life Sciences, Physiology

Parasitoids have an exceptional lifestyle where juvenile development is spent on or in a single host insect, but the adults are free-living. Unlike parasites, parasitoids always kill their host. How parasitoids use such a limiting resource, particularly lipids, is important for their chances to survive and reproduce. In part 1, we describe the parasitoid lifestyle, including typical developmental [...]

A call to expand global change research in LTER coastal wetlands

Alex C Moore

Published: 2023-06-30
Subjects: Ecology and Evolutionary Biology

Global change stressors are altering the structure of ecological communities with significant implications for the functions and services that ecosystems provide. Coastal zones are particularly susceptible to such stressors, yet our collective understanding of the long-term effects of global change on these systems and, in particular, the consumer species found within them, is limited. The US [...]

Too simple, too complex, or just right? Advantages, challenges and resolutions for indicators of genetic diversity

Sean Hoban, Jessica da Silva, Alice Hughes, et al.

Heterogeneous dispersal networks to improve biodiversity science

Paul Savary, Jean-Philippe Lessard, Pedro R. Peres-Neto

Published: 2023-06-21
Subjects: Biodiversity, Ecology and Evolutionary Biology, Life Sciences, Population Biology, Terrestrial and Aquatic Ecology

Dispersal plays a key role in shaping spatial patterns of biodiversity, yet its spatial heterogeneity is often overlooked in biodiversity analyses and management strategies. Properly parametrized heterogeneous dispersal networks capture the complex interplay between landscape structure and species-specific dispersal capacities. This heterogeneity, however, is recurrently neglected when studying [...]

Griffon Vultures restrict movements around roosts and supplementary feeding stations, even when carrion is available on the field: a call for wind energy zonation to avoid ecological traps on Mediterranean islands

Jacopo Cerri, Ilaria Fozzi, Davide De Rosa, et al.

Published: 2023-06-19
Subjects: Behavior and Ethology, Ecology and Evolutionary Biology, Environmental Engineering

Wind energy is developing on Mediterranean islands, where endangered populations of Griffon Vulture (Gyps fulvus) occur. As griffons are subjected to collisions with wind turbines while foraging, it is necessary to understand which factors affect their movements, to minimize the potential impact of wind farms. We assessed habitat use by 37 griffons (n. GPS locations = 130,218) and its overlap [...]
